Since the proposed work is not for compensatory mitigation and meets the Division's definition of stream restoration, no written authorization is required to use Water Quality General Certification No. 3353. As such, this project may proceed without written approval from the Division. Please keep in mind that, while written authorization is not required, you are still covered under GC #3353 and you must adhere to the conditions of that Certification. A copy of GC #3353 has been enclosed for your reference. If you have any questions regarding this matter, please contact Mrs. Jennifer Frye at (336) 771-4600, ext. 275.
